Clinical Study Results
The diagnostic categories of The Bethesda System were used as the basis of the comparison
between conventional and ThinPrep™ findings from the clinical study. The diagnostic
classification data and statistical analyses for all clinical sites are presented in Tables 2 through 11.
Cases with incorrect paperwork, patient’s age less than 18 years, cytologically unsatisfactory
slides, or patients with a hysterectomy were excluded from this analysis. Few cases of cervical
cancer (0.02%
3
) were represented in the clinical study, as is typical in the United States patient
population.
